Abstract:

Finely-dispersed phosphors of Y2O3:Eu and Y3Al5O12:Eu have been synthesized with the help of Pechini method and the method of self-propagating high-temperature synthesis (SHS). During the synthesis of phosphors on the basis of Y2O3 carried out with Pechini method the size of crystallites increases with the enlargement of concentration of yttrium, but it decreases when the method of SHS is applied. The structure of phosphors on the basis of Y3Al5O12 (YAG) is strongly amorphized. This fact agrees with the data of XRD and with the prevalence of the band with λmax = 613 nm in the spectra of this p

Abstract:

Y2O3:Eu is a promising red-emitting phosphor owing to its high luminance efficiency, chemical stability, and non-toxicity. Although Y2O3:Eu thin films can be prepared by various deposition methods, most of them require high processing temperatures in order to obtain a crystalline structure. In this work, we report on the fabrication of red Y2O3:Eu thin film phosphors and multilayer structure Y2O3:Eu-based electroluminescent devices by atomic layer deposition at 300 °C. The structural and optical properties of the phosphor films were investigated using X-ray diffraction and photoluminescence me

Abstract:

We synthesized nano-sized Eu-doped Y2O3 (Y2O3:Eu) phosphor powder by an ion-exchange po-lymer/water/oil (W/O) emulsion method using carboxymethyl cellulose (CMC) as the ion-exchange polymer, in which the CMC-(Y, Eu) gel formed was calcined at 800°C in air to convert into Y2O3:Eu particles. The obtained phosphor powder consists of unagglomerated particles with sizes in the range of 30-80 nm and exhibits strong red emission at 612 nm. This CMC/W/O method for producing nano-sized oxide powder has significant advantages over conventional solid-phase and chemical solution-based methods because this

Abstract:

The luminance level of thin film Y2O3:Eu3+ phosphors deposited by a pulsed laser deposition (PLD) technique are not acceptable for field emission display (FED) because of so-called wave guiding effect. Corrugated glass plates were employed as a substrate in order to relieve the wave guiding effect and in turn improve light extraction efficiency of Y2O3:Eu3+ thin film phosphors. Integrated photoluminescent efficiency, film surface roughness and crystallinity were monitored as function of the pitch of corrugation. The integrated photoluminescence efficiency of Y2O3:Eu3+ thin film phosphor deposi

A new series of YBiW2O9:Eu[Formula: see text] phosphors were successfully synthesized by the solid-state reaction method for the first time. Pure phase formation of YBiW2O9:Eu[Formula: see text] was confirmed by X-ray powder diffraction. It is found that the 7F[Formula: see text]L6 transition results in the strongest near-ultraviolet excitation centered at 395 nm and the phosphors show strong electric-dipole (ED) transitions (5D[Formula: see text]F[Formula: see text] with red emission peaking at 616[Formula: see text]nm.

Abstract:

High resolution and high efficiency planar display, one of the national priorities for advanced technologies and commercial applications, require highly efficient phosphor materials with crystalline monodispersive fine particles [1,2]. Europium oxide activated yttrium oxide (Y2O3:Eu) is a potential red-emission phosphor powders to be used in high efficiency electroluminescence and field emission displays. In this paper, a novel hydrolysis technique is employed to prepare phosphor particles of Y2O3: Eu, and the structure characterization is reported.In this synthesis technique, urea reacts with

Abstract:

Photodynamic therapy (PDT) is a promising modern method for treatment of oncological, bacterial, fungal and viral diseases. However, its application is limited to diseases with superficial localization since the body tissues are not transparent for visible light. To address this problem and extend PDT application to abdominal diseases, an enhanced method of X-ray photodynamic therapy (XRPDT) is suggested, involving X-ray radiation easily penetrating the body tissues. The implementation of this approach requires the development of a pharmacological drug including a photosensitizer stimulated by
